+# 🔄 Infinity CICD Loop System
+
+An autonomous, self-improving continuous research and development system that never stops learning.
+
+## Quick Start
+
+```python
+from codegen.infinity_loop import InfinityLoopOrchestrator
+
+# Initialize
+orchestrator = InfinityLoopOrchestrator(
+    api_key="your-api-key",
+    org_id=323
+)
+
+# Define context
+context = """
+Current System: My application
+Goal: Continuously improve performance and features
+Repository: org/repo
+"""
+
+# Run single loop iteration
+execution = await orchestrator.run_loop(context)
+
+# Or run continuous loop
+await orchestrator.run_continuous_loop(context, max_iterations=10)
+```
+
+## The Infinity Loop

+
+## Stages
+
+### 1. 🔬 Research Agent
+**Purpose**: Discover improvement opportunities
+
+**Process**:
+- Analyzes current system state
+- Researches SOTA (state of the art) solutions
+- Searches academic papers, GitHub repos, blogs
+- Identifies specific optimization opportunities
+- Generates detailed PRD
+
+**Output**: Research Report + PRD
+
+### 2. 📊 Analysis Agent
+**Purpose**: Validate feasibility and plan implementation
+
+**Process**:
+- Validates technical feasibility
+- Estimates implementation cost/effort
+- Identifies risks and blockers
+- Designs implementation strategy
+- Defines success metrics
+
+**Output**: Analysis Report with Implementation Plan
+
+### 3. 💻 Implementation Agent
+**Purpose**: Generate code changes
+
+**Process**:
+- Generates all necessary code changes
+- Writes comprehensive tests
+- Creates clear documentation
+- Prepares PR description
+
+**Output**: Implementation ready for PR creation
+
+### 4. 🧪 Test Agent
+**Purpose**: Validate changes work correctly
+
+**Process**:
+- Runs full test suite
+- Runs performance benchmarks
+- Runs security scans (trufflehog, etc.)
+- Checks code quality (linting, type checking)
+
+**Output**: Test Report (PASS/FAIL)
+
+### 5. 🔧 Fix Agent (Conditional Loop)
+**Purpose**: Resolve test failures
+
+**Process**:
+- Analyzes all test failures
+- Identifies root causes
+- Generates fixes
+- Re-runs tests
+
+**Loop**: Repeats up to 5 times until tests pass
+
+**Output**: Fixed PR
+
+### 6. 📈 Benchmark Agent
+**Purpose**: Compare performance vs baseline
+
+**Process**:
+- Runs performance profiling
+- Measures resource usage (CPU, memory, etc.)
+- Compares against baseline metrics
+- Calculates improvement percentages
+
+**Output**: Benchmark Report with comparison
+
+### 7. 🎯 Integration Agent
+**Purpose**: Decide whether to integrate changes
+
+**Decision Logic**:
+```python
+if improvement > 5% and no_regressions:
+    merge_pr()
+    update_baseline()
+    record_success()
+    continue_loop()
+else:
+    close_pr()
+    record_failure()
+    learn_from_failure()
+    continue_loop()
+```
+
+**Output**: Integration decision + learnings
+
+## State Persistence
+
+All loop executions are persisted to SQLite database at `~/.codegen/infinity_loop.db`.
+
+**Schema**:
+```sql
+CREATE TABLE loop_executions (
+    loop_id TEXT PRIMARY KEY,
+    stage TEXT NOT NULL,
+    iteration INTEGER NOT NULL,
+    start_time TEXT NOT NULL,
+    end_time TEXT,
+    research_report TEXT,
+    analysis_report TEXT,
+    pr_number INTEGER,
+    test_report TEXT,
+    benchmark_report TEXT,
+    integration_decision INTEGER,
+    baseline_metrics TEXT,
+    new_metrics TEXT,
+    improvement_pct REAL,
+    error_count INTEGER,
+    last_error TEXT,
+    created_at TEXT,
+    updated_at TEXT
+)
+```
+
+## Configuration
+
+Configure via environment variables:
+
+```bash
+export CODEGEN_API_KEY="sk-..."
+export CODEGEN_ORG_ID="323"
+```
+
+Or pass to constructor:
+
+```python
+orchestrator = InfinityLoopOrchestrator(
+    api_key="sk-...",
+    org_id=323
+)
+```
+
+**Constants**:
+- `MAX_FIX_ITERATIONS = 5` - Max test/fix cycles
+- `IMPROVEMENT_THRESHOLD = 0.05` - 5% improvement required
+- `STATE_DB_PATH = ~/.codegen/infinity_loop.db` - State database location
+
+## Examples
+
+### Single Loop Iteration
+
+```python
+import asyncio
+from codegen.infinity_loop import InfinityLoopOrchestrator
+
+async def run_single():
+    orchestrator = InfinityLoopOrchestrator()
+
+    context = """
+    Current System: E-commerce API
+    Goal: Improve response times and reduce database queries
+    Repository: myorg/ecommerce-api
+    """
+
+    execution = await orchestrator.run_loop(context)
+
+    print(f"Loop ID: {execution.loop_id}")
+    print(f"Stage: {execution.stage.value}")
+    print(f"Integrated: {execution.integration_decision}")
+    print(f"Improvement: {execution.improvement_pct}%")
+
+asyncio.run(run_single())
+```
+
+### Continuous Loop (10 iterations)
+
+```python
+import asyncio
+from codegen.infinity_loop import InfinityLoopOrchestrator
+
+async def run_continuous():
+    orchestrator = InfinityLoopOrchestrator()
+
+    context = """
+    Current System: Machine Learning Pipeline
+    Goal: Continuously optimize model performance and inference speed
+    Repository: myorg/ml-pipeline
+    """
+
+    # Run 10 iterations
+    await orchestrator.run_continuous_loop(context, max_iterations=10)
+
+asyncio.run(run_continuous())
+```
+
+### Query Loop History
+
+```python
+from codegen.infinity_loop import LoopStateManager
+
+state_mgr = LoopStateManager()
+
+# Get recent executions
+executions = state_mgr.list_executions(limit=10)
+
+for exec in executions:
+    print(f"{exec.loop_id}: {exec.stage.value} - {exec.improvement_pct}%")
+
+# Get specific execution
+execution = state_mgr.get_execution("loop_1733598523")
+print(execution.research_report)
+```
+
+## Benefits
+
+✅ **Fully Autonomous** - No human intervention required  
+✅ **Self-Healing** - Automatically fixes test failures  
+✅ **Continuous Learning** - Each iteration improves on the last  
+✅ **Persistent State** - Survives restarts and crashes  
+✅ **Quality Gates** - Only integrates if improvement > 5%  
+✅ **Risk Mitigation** - Tests, benchmarks, and validates before merging  
+✅ **Audit Trail** - Full history of all decisions and changes  
+
+## Architecture
+
+Built on top of:
+- **Codegen Agent Execution** - All agents use Codegen SDK
+- **Async/Await** - Non-blocking parallel execution
+- **SQLite** - Lightweight persistent state
+- **Modular Agents** - Each stage is independent and replaceable
+

+- [ ] Multi-repository support
+- [ ] Web dashboard for monitoring
+- [ ] Slack/email notifications
+- [ ] Advanced learning from past iterations
+- [ ] Cost optimization and caching
+- [ ] Parallel multi-loop execution

+
+## When to Use
+
+**Use Infinity Loop when:**
+- You want continuous autonomous improvement
